Green grass carp is a new type of grass carp breeding technology, do you know its benefits?

Grass carp culture is an ecological and healthy breeding mode that follows the ecological habits of grass carp and the ecological characteristics of fish ponds, and builds grass carp "Hui" shaped ecological breeding ponds, and uses ryegrass, millet grass and Sudan grass planted on the flat beach and pond ridge in the pond as natural bait for grass carp, and matches a certain proportion of silver carp, bighead carp, herring, crucian carp, yellow catfish and other seedlings, supplemented by feeding artificial compound feed to raise grass carp.

First, the effect of energy conservation and emission reduction:

In March every year, ryegrass or millet grass is planted on the flat beach and ridge of the curved pond, and then water is gradually added to the depth of about 15 cm, so that the grass on the flat beach is partially submerged in water, and the grass carp can graze freely on the flat beach. This not only allows the grass carp to eat tender and delicious grass, but also effectively saves manpower for harvesting and feeding the grass. Starting in June, Sudan grass is planted on the ridge of the pond, and the growth of Sudan grass is accelerated by applying bottom fertilizer, and three stalks are grown in Sudan grass, and the grass carp can be harvested and fed.

Ryegrass and millet grass only need a small amount of organophosphate fertilizer without spraying pesticides during the growth process, while Sudan grass only needs a small amount of high-efficiency and low-toxicity drugs to control the main disease aphids during the growth process. Ryegrass, millet grass and Sudan grass are grown with no or less pesticides and fertilizers, which not only saves the cost of pesticides and fertilizers, but also causes almost no environmental pollution.

In addition, the feces discharged by grass carp after ingesting green fodder are decomposed into fertilizer water through biological fertilizer, which becomes natural bait for polyculture of silver carp, thereby increasing the yield of silver carp.

Second, in terms of economic benefits:This model dramatically reduces feed costs. Through photosynthesis, solar energy is converted into animal protein in situ, and its fish farming cost is 30% to 40% lower than that of conventional fish farming.

Effectively saves labor costs. The green is fully absorbed and utilized by the mineral nutrients of the fish pond silt, thereby improving the soil. At the same time, the use of pond ridges to plant grass, easy to water, on-site feeding, reduce labor costs.

It can improve the nutritional quality of grass carp. The grass carp bait is mainly green fodder, and the grass carp cultivated is beautiful in shape, good taste, rich in nutrition and pollution-free, and is widely favored by consumers. Reduce the occurrence of fish diseases.

Green fodder is fed to grass carp, which is easy for grass carp to digest and absorb, which can reduce the occurrence of grass carp fatty liver, enteritis and other diseases, thereby reducing the input of fishery medicine.

3. In terms of ecological benefits:The bait fed in this mode is mainly green fodder, which reduces the feeding of artificial compound feed, which reduces the accumulation of nutrients such as nitrogen and phosphorus in water and sediment caused by feed use. No or less chemical fertilizers and pesticides are applied in the process of planting green, which is friendly to the ecological environment.

Cultivating green fish reduces the occurrence of grass carp diseases, reduces the number of uses and amounts of fishery medicines, and ensures the quality and safety of aquatic products.

The green grass carp breeding model in the shape of the pond is energy-saving and emission-emission, and also has high economic and ecological benefits, which is a grass carp breeding model worthy of promotion and application.

I understand some of its benefits, the new breeding technology of green grass carp in the return pond can save energy and reduce emissions, and achieve harmony between man and nature.

1. Breeding area herring breeding, to choose the appropriate breeding area, around the pond to have sufficient water sources, water quality to reach a certain standard, so as to facilitate the fish pond discharge work. In addition, the transportation should be more convenient to facilitate the management of the pond.

2. Pond cleaning Before we carry out the breeding work, we must carry out a more thorough cleaning of the entire pond. First of all, we need to drain the water in the pond. Remove some of the silt from the bottom of the pond and put it back in the water.

After that, we should not be too anxious to put the fish fry, we should first carry out the disinfection work of the river water, and use some drugs to cultivate the water fertile, and measure the pH value in the water to ensure that the environment in our water, as well as all aspects of the conditions can meet the needs of herring growth. Herring farming technology.

3. Fish fry purchase Fish fry must be selected to be strong and sturdy, the specifications are similar, only such fish can be a batch out, and the physical condition will not be much different, so as to ensure that we will not have a lot of bad conditions in the later breeding process. After the fry are purchased, they must be disinfected with some corresponding drugs, and when the fry are stocked, we try to choose a time when the weather is warmer, and we do not need to put other bait within a day or two after the fry are just released.

4. Feed feeding in the later stage of feed feeding, we must pay attention to the position and time of each feeding to be fixed, which helps fish develop a good eating habits, for the feed, to ensure that it is excellent, there can be no mold and deterioration, and the protein in the feed can not exceed 25%. Different seasons are fed differently, summer fish physical energy consumption is large, so a day to feed 4 times, autumn can be appropriately reduced the number of feeding, and each feeding amount is not too large, under any conditions, we feed must be fed within three hours to eat, can not be wasted.

5. Daily management rainy weather, the pond may cause insufficient feeding, this time you can turn on the aeration equipment, so as to provide sufficient oxygen to the fish, especially the small fry into the mid-term rapid growth stage, to maintain a quantitative increase in oxygen every day, a fixed time to replace the water source, in the summer you can add some water to the pond, when the water quality deteriorates to increase the quality of water exchange.
